V'is e fe'eding mechanism.After a broom is vised the'vise is pushed tothe rear until it is 'in position for the first stitch. The vise-isstopped in position for the firstv stitch by. a device which isautomatically adjustable, ac-

- cording to the width of the broom, as will be hereinafter explained; Abar 36 has its forward end connected to an arm 37 extending out from thevise-frame, and its rear endpasses through a' box- 38, in which it is engaged by, a clamping-jaw 39, Figs. 4'a-nd 7. The jaw' 39 isperiodicallyclamped on the bar by pressure ofa 'pin or bolt 40, carriedby acam-lever 41, which bears a'roll 42, ri'dmg on a cam-rlb 43 on. acam-cylinder 44,

Above the rod 36 isa parallel rod 45, which also passes through the brx38 and-is periodically clamped similarly to the rod 36 by a'pinor bolt46, cam-lever 47, and a cam-roll 48, hearing on cam-rib 49. 47 are heldtothe [cams by springs 41 and The rods 36 and 45 are bow-lever, whichhas ahorizontal ,arm or extension 51. The elbow-leverturns about a pivot52, connected to the lower rod, and the arm 50 'is normally drawnforward by 'a on the vise-frame.

In the operation of the inachine the rods 36 and 45 are alternatelycla-i'nped and alter natelyreleased. 'hen the rod 45 is released.

The eye isprovided with a hook or support 75", .in which the thread is placed 1erates by the operatorbel'orethe first 'stite-h is taken. The lelt-handthreading device (illustrated in Fig. 1 11 is cmistrueted and'operatedin the same manner as the right-hand device, with the exception that itsparts are inverted, and it has no tln'ead-stmpoi't, such as 75.

.iutomtltir starting (It ,Ulflq POWOI is applied to a driving-pulley 81, which normally runs idle. This pulley is engaged and dis connectedl'rom'the driving-shaft 71. by a eluteh of suitable construction, whichclutch is operated by a clutch-lever S5, pivoted at so. Fig. 3. Theclutch-lever is connected by a link so with an elbow-lever 87 and aspring SS. l ig. b, constantly tends to draw the clutch-lever forward tothrow in the clutch and start the machine. The clutch is normally heldopen by astop 89, which engages a shoulder 90 on link 86. The stop 89 isthrown into the path of said shoulder by a spring $11, which isconnected to a'lever 92, to which said stop is pivoted. When the stop 89is withdrawn from the shoulder 90,

the spring 88 immediately closes the clutch and starts the machine. Themachine is arranged to automatically start sewing when the broom is inposition for the first stitch. This position varies with the width ofthe broom, and means are thereforeprovided for starting which aregoverned by the width of the broom. v

Rei'errin to Figs. 3, 4, and 5, 93 indicates a pair of hngers orthread-supports which engage the forward and rear edges of the Thesefingers are pivoted to arms 91, which are connected and drawn towardeach other by a spring 95. Each of the fingers 93 has a downwardextension 96, which isnormallyheld against a pin'97 by aspringtlS. Thelingers are thus held normallyin position to engage the edges ol thebroom just above the vise. Each of the arms 94 is provided with anantitrictita'i-roller 99, which engages a cam-surface on the left-handvise iaw. hen the vise is thrown open. these eams throw back the-lingers$13 from the vise to permit a broom of any width to be inserted. Thecam-rollers tttl are adjusthen the arm st arts to move l'orzontalextension 1111, provided on its rear end with an inclined toothedsurl'aee 102. which surl'aee is adjusted up and down. aecording to thewidth ol' the broom in the vise. A lever 103, pivoted to.,the vise at104. has

at its lower end an adjustable tooth 111.3.

able with relation to the arms 9- so that the lingers 113 may be thrownback to dill'erent distances.

Thelower end of thisrock-shalt carries an arm 109, which hasa piit-and-slot connectionwith alink 111), which is rigid with the stop Sil The automatic startingoi themachine up as follows: As the'vise is closed the fingers 98 engage. thejaws ol the broom. and the toothed suriaee 102 is adjusted aeeording tothe width oi the broom. The vise is then moved to the rear to beginsewing. As it reaches the proper starting position one ol' the teeth 102engages the tooth 107) and moves it rearward, slightly rocking the shalt10S, Figs. 3,1-1, and S, and drawing the stop 89 away lrom the shoulder11), thus permitting the spring on to immediately throw in the clutchand start the maehine.

1 rod 122 is drawn lorward' by the vise. and its positionl with relationto the vise depends upon the width ol' the broom. as will be evidentl'rom an inspection ol' .l' ig'. -1. The stopping ot' the maehine istherel'ore regulated by width of the broomiii mueh the same S9'engagesthe shoulder tit) and preventsthe manner as the starting is soregulated. To

efl'ect the disengagement of therod 122 from the pin 120 at theproper-momentjust as p the clutch is released.a lever 140, Figs. 3, 5 8,9, is provided. The lower end of lever 140 is tied to lever 92 by aspring 141, and its upper end has an inclined edge 142.v I/Vhen lever92- moves to the rightat the instant the clutch is opened-the edge 142raises the rod 122 from pin 120, as shown in .Fig. '9.

The machine may be started and stopped by hand whenever desired, forwhich purpose a hand-lever 123, Figs. 1, 3, and 8, is pro vided. Thislever is pivoted concentrically 1:5 withthe lever 87, and-its rear end123 is arranged to bear against said lever 87. Lever 123 is normallyheld in the position shown in Fig. 8 by spring 124. 'hen, thelever'123is moved to the right, it rocks lever 87 and stops the machine.hen lever 123 is moved to the leftinthe direction of the arrow, Fig.8,it rocks the lever 92 hymeans of a connecting-link 125 and withdrawsthe sto 89, thus starting the machine. To effect quick stoppage of themachine after each row of stitches, I have a brake which isaa1tomatically applied. The brake devices are shownin Figs. 1,14, and,15. On opposite sides of the fly-wheel 70 are brake-lelfivers 130,which are provided with suitable brake-shoes. Springs v131 tend to holdthe shoes free from thewheel. A link 132 is con- Fected with one lever130 and has an opening thrc ugh which the free end of the other leverpasses. Pivoted to link 132 is a lever'having its longer arm 133connected by link 134 with the arm .87 and its shorter arm 135 bearingonthe end of the lever 130, which passes through link 132. It will beevident that when the lever 87 movesrearward to open fully drawntogether and'clamped upon the wheel 70, and the machine thereby stopped.
